This is my next power bank.
The Anker Prime 27,650mAh Power Bank (250W).
My Ambrane keeps a phone topped up without complaint and buckles the moment a laptop asks. This is the bank built for the day both need charging at once.”
The wattage a laptop asks for
My Ambrane caps at 100W, and even that gets shared awkwardly the moment a second device joins in. Plug a laptop and a phone in together and the laptop crawls while the phone barely speeds up. The Anker pushes up to 140W down a single USB-C line, close to wall speed for a MacBook Pro, and it holds proper wattage on both USB-C ports at once. Most days I won’t come close to using that.
A screen instead of a guess
The Ambrane has one white LED that means "some charge left," which isn’t information. The Anker’s display counts the percentage, the watts leaving each port and the minutes to full. I’d stop unplugging a laptop early because I assumed the worst.

Two ports doing laptop wattage at once, a display that tells you something, enough capacity for a full laptop charge with room left665 grams is a lot to add to a bag, and it costs as much as a decent phone |
UGREEN Nexode 20000mAh 100W, if 27,650mAh is more brick than you need to carry. Same idea, half the size, still enough for a laptop top-up.
Anker’s 43-minute recharge figure assumes a 140W USB-C charger I don’t currently own, so my actual recharge time will depend on what I plug it into, not the spec sheet number.
That link is an Amazon.in search, not one exact listing: I haven’t pinned a specific product page until I’ve verified it matches this configuration. If you buy through that link I earn a small commission. It costs you nothing and keeps the picks independent. I accept long-term review units; they never buy the pick, and I say so when a unit was loaned.
Is 99.5Wh allowed on a flight?
Yes, it sits just under the common 100Wh carry-on limit most airlines and India’s own rules use, which is clearly why Anker built it to that number rather than higher. I’d still keep the spec sheet handy for security if asked.
Do I need 250W if I mostly just charge a phone?
No. If a phone is 90 percent of your charging, the smaller UGREEN or Stuffcool bank does that job for a fraction of the weight and price. I want this for the days a laptop needs charging too.
Is 665 grams too heavy to carry daily?
You notice it, well past what a phone-only bank weighs, and I won’t pretend otherwise. I’m accepting that because the alternative is a laptop dying mid-session with a bank in the bag that can’t save it.
